I just bought one of the listings here. It claimed a profit of $14.05 with a Buy price of 22.95 and a Sell price of $37.

Some notes:

- The "Buy" and "Sell" locations were the same website. Immediately raised some concerns (why would the same entity want to screw itself over by buying the same book it's selling for more money?)

- Upon inspection, it's because to be eligible for the Buyback price of $37, the book must not have tears, highlighting, or missing pages.

- The books at the Buy price of $23 or less have all been noted as just "Acceptable" condition with missing pages and highlighting. The books at better conditions are all $50+.

- Wasted $3.
